Porous Graphite Applications Across Industries

Porous graphite is a precision engineered material with controlled porosity and high thermal stability, enabling critical performance in the most demanding industrial processes.

Semiconductor Industry

In power semiconductor manufacturing, porous graphite is a key structural component inside SiC single-crystal growth furnaces. Operating above 2,400°C in corrosive atmospheres, it delivers the precise, uniform vapor permeability needed to regulate SiC flux and sustain crystal quality — making it essential to the production of power chips for electric vehicles and 5G infrastructure.

Photovoltaic Industry

In photovoltaic silicon production, porous graphite is used within the hot zones of Czochralski (CZ) crystal pulling furnaces. Its open-cell structure supports controlled atmosphere distribution and thermal management during high-temperature crystal growth, directly influencing the uniformity and electrical performance of monocrystalline solar wafers.

Metallurgy

In metallurgical processing, porous graphite serves as a gas injection and diffusion medium in molten metal degassing systems. Its uniform pore structure generates finely distributed bubbles that remove dissolved gases from liquid steel and non-ferrous alloys, reducing porosity defects and improving the mechanical properties of finished castings.

Chemical Industry

Porous graphite's resistance to concentrated acids, alkalis, and oxidizing agents makes it well suited for aggressive chemical process environments. It functions as a porous body in graphite heat exchangers and as a gas sparger in reactors — including HCl synthesis units and acid concentrators — providing consistent flow distribution and long-term structural integrity.
